A-WEIGHTED SOUND LEVEL. An A-weighted sound level is a sound level in the 1,000 to 797
6,000 Hz frequency range that is increased by 10 dB if the noise event occurs between 10:00 p.m. 798
and 7:00 a.m. The A-weighted sound level reflects the greater intrusiveness of sounds that the ear 799
perceives as louder compared to other frequencies. “dBA” or “dB(A)” indicate a sound level 800
measurement has been A-weighted. 801
802
DAY-NIGHT AVERAGE SOUND LEVEL. The day-night average sound level is the noise 803
exposure in areas around airports (abbreviated as “DNL” in text and “L
RR

RR
”
in equations). DNL is
804
a measure of the average A-weighted sound level of all aircraft flights occurring in a 24-hour 805
period. 806

constructed with sound insulation or other means to achieve a DNL of 45 dBA or less inside 827
the building: Group E occupancies; Group I-1, I-2 and I-4 occupancies; and Group R 828
occupancies. If the cost of modifications to an existing building is 75 percent or more of the 829

Fire Code. 4318
4319
3. In I Occupancies provided with an approved automatic sprinkler system 4320
throughout, the release button will not be required provided a control for 4321
releasing the device is provided at a nurse station and a deactivation method, 4322
e.g. a keyed control, a control pad or card reader, is provided at the door and 4323
staff is supplied with the appropriate tool or knowledge to operate the 4324
release mechanism. 4325
4326
1010.2.11.5 Automatic release mechanisms. Electronic locking devices shall have 4327
automatic releasing that complies with the following: 4328
4329
1. Automatically release upon activation of the smoke detection or fire alarm 4330
system, if provided. The control devices shall remain unlocked until the system 4331
has been reset. 4332
4333
2. When the area of concern has a sprinkler system, automatically release upon 4334
activation of a waterflow alarm or trouble signal. The control devices shall 4335
remain unlocked until the system is reset. 4336
4337
3. Automatically release upon loss of electrical power to the building or to the 4338
electronic device. Locking mechanisms shall not be provided with emergency 4339
backup power such as generators or batteries. 4340
4341
4. Automatically release upon activation of a manual release mechanism as 4342
specified in Section 1010.11.2.4 and as further specified in Section 1010.11.2.7. 4343
4344
Manually resetting the devices is not required. Automatically resetting the devices 4345
may be done by zone. 4346
4347
1010.2.11.5.1 Zone control. Deactivation of the device(s) may be zone controlled 4348
as follows: 4349
4350
1. All devices on the same floor as the source of activation in fully sprinklered 4351
buildings. 4352
4353
2. All devices on the same floor as the source of activation of the smoke 4354
detection system plus one floor below and all floors above in unsprinklered 4355
buildings. 4356
4357
(Note: When security is still desired after the automatic release of the 4358
system, or when positive latching is necessary for fire door installation, it is still 4359
possible to maintain security provided the appropriate combination of devices 4360
is installed. As an example, use of panic hardware or doorknobs that provide 4361

mechanical exiting at all times, but do not function from the exterior unless 4362
electronically activated, will still provide a secured door. It will provide the 4363
required manual exiting but entry by card or code is not available until the 4364
system resets. 4365
4366
No such provision of restricting entry can be used when passage through 4367
the device is necessary for access to the exit. As an example, when the elevator 4368
lobby is secured from the exit stairs by a full floor tenant, upon automatic 4369
activation those devices shall release and access be provided through the tenant 4370
space to the stairs. A manual locking system cannot be installed to insure 4371
security.) 4372
4373
1010.2.11.6 Door swing freely/single exit motion. Doors shall swing freely when the 4374
device is released. 4375
4376
(Note: It is required that the exit motion require only one activity. With normal 4377
doors, one activity is pushing the mechanical panic bar or turning the mechanical 4378
doorknob. With an electronic device, one motion is pushing the button; therefore, 4379
pushing the button and pushing a panic bar or turning a doorknob would be two 4380
activities. An acceptable alternative is to use a motion detector (push button is still 4381
required). The motion detector will release the device upon approach and turning the 4382
doorknob is now just one activity. The push button is only necessary should the motion 4383
device fail. Another option is to use an electronic panic bar. One motion, pushing the 4384
bar, is for exiting but entry is controlled. Or, use of an electronic doorknob where 4385
exiting is always mechanical but the entry side does not engage without electronic 4386
activation.) 4387
4388
Exception: When doors are required to have positive latching, the building official 4389
and fire chief shall determine: 4390
4391
1. if a double motion to exit, i.e. the release of the electronic device then the 4392
operation of a door knob or push bar, is an acceptable exit means; or 4393
4394
2. if the latch should be designed to fail in the secure position; or 4395
4396
3. whether to deny the usage of the locks. 4397
4398
1010.2.11.7 Request to exit buttons/break glass boxes/emergency pull boxes. Exit 4399
buttons, break glass boxes and emergency pull boxes shall be installed as follows: 4400
4401
1. Button. The release button shall be red in color and at least a 2-inch mushroom 4402
switch or two-inch square lexan palm button. 4403
4404
2. Location. The button, break glass box or emergency pull box shall be located 4405

electronics, and the device shall remain unlocked for a minimum of 30 seconds. 4418
It shall not be required that the release mechanism be constantly held, such as 4419
holding down the button, to get out. 4420
4421
(Note: When buzzing someone out, holding down the button is acceptable; 4422
however, the manual release device installed at the door, even those required in 4423
the occupancy using buzzing, shall not require constant holding down to exit.) 4424
